深静脉血栓患者C反应蛋白1059G/C基因多态性的研究

摘要

本研究旨在探索C反应蛋白(C-reactive protein,CRP)1059 G/C基因多态性在深静脉血栓(deep vein thrombus,DVT)中的分布及其临床意义.应用聚合酶链反应-限制性片段长度多态性(polymerase chain reaction-re-striction fragment length polymorphism,PCR-RFLP)基因分型技术检测61例DVT患者和60例对照组CRP 1059G/C基因多态性,并统计各基因型及等位基因的频率.结果显示,病例组CRP 1059G/C基因型及等位基因突变频率与对照组比较差异无统计学意义(p＞0.05).结论:CRP 1059 G/C基因多态性存在一定的人种及地域差异,是否是DVT患者遗传性危险因素尚有待进一步研究.%This study was aimed to investigate the distribution of 1059 G/C gene polymorphism of C-reactive protein (CRP) in deep vein thrombus (DVT) and its clinical significance.Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to screen 1059 G/C polymorphism in exon 2 of C-reactive protein gene in 61 cases of DVT and 60 healthy controls.The frequency of mutation was calculated.The results showed that there was no statistical difference of 1059 G/C genotype and mutation frequency of allele between deep vein thrombosis group and control group (p ＞0.05).It is concluded that the 1059 G/C gene polymorphism of CRP displays certain difference in races and areas, and whether 1059 G/C gene polymorphism of CRP is a dangerous factor for deep vein thrombosis, which needs to be deeply explored.
